CUTLER-TUBE.

Specification of Letters Patent.

Patented Oct. 8, 1912.

T 0 all whom it may concern Be it known that I, CHARLES Mums, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Goiler-Tubes, of which the followin is a specification.

Drawing 'rames are usually set up in gangs, a number of them being connected up in a row with a common power shaft and means common to all the frames for distributing power to run the various d 'awing rolls and coiling and can rotating mechanism. Thus a number of slivers are acted upon at once. The value of such a machine depends upon its certainty of operation, its evenness of wear and its simplicity of con struction, this last feature being of particular importance because of the necessity for keeping the moving parts clean, 2'. 6. free of the lint and dirt which always exist when cotton is being treated.

My present invention relates to the coiler tube, its connections and operation, my purpose being to simplify and reduce the amount of mechanism heretofore considered necessary and so arrange it as to reduce 'l'riction and at the same time strengthen the frame and prevent any undue lengthwise strain on the shaft.

The rotation of the coiler tube has been accomplished heretofore by a horizontal shaft running the length of the machine and at suitable points carrying a gear which engages one of a train of gears by which the necessary movement is given to the coiler tube gear. Such an arrangement is cumbersome because of the room which the train of gears requires. Moreover the larger the number of gears used the greater is the possibility of accumulating fly and lint in the moving parts, however the parts may be carried. Such accumulation has to be removed and this requires shutting down the machine and perhaps the removal of the gears themselves. A reduction therefore of the moving parts is one of importance both in the matter of first cost and also in the economical running of themachine, constant production being required of it and hence as little stoppage for cleaning and repairing as may be. Moreover in the usual construction no especial provision is made to hold each shaft gear to its work and hence there is a general tendency to give to the shaft as a whole an endwisc thrust which causes increased friction and wear upon the moving parts. It is to overcome this diiliculty, reduce the number of moving parts, simplify the manner of cleaning and repairing, and make a practically noiseless machine that my invention has been made as well as to strengthen the frame, and it consists in such a reduction, rearrangement and reconstruction of parts that a gear upon the driving shaft acts directly upon the coiler gear, with corresponding results pointed out below.

My invention will be understood by reference to the drawings in which is shown a drawing f 'ame isolated from its neighbors all of which, however, are alike except as an end frame will require a power pulley, etc.

Figure 1 is a section on line 1.--1 of Fig. 2, showing also a portion of a can and also the sliver feeding mechanism. Fig. 2 is a plan of my coiler. Figs. 3 and 4 are sections on lines 3-3 and 4-4 of Fig. 2.

A is the coiler plate which is bolted to the front of the frame B of the machine by bolts 0. This plate is recessed at I) to form a channel running the length of the entire machine in which is supported the driving shaft C which also runs the length of the machine. A number of these coilers, usually five or six, are generally set up together, a single shaft driving them all. The shaft C is supported in a bearing D bolted to the coiler plate by bolts (Z. A hole (Z is pro vided in each bearing for purposes of lubrication. The coiler plate A is also recessed as at E to provide a cavity for a gear F, the cavity being sufficiently large to allow the gear to be adjusted more or less lengthwise the shaft and being constructed to inclose the gear as much as possible from dust and yet allow an opening through which the fly, etc., may be brushed from it. It will be noted that these so called recesses are the. result of bows or arches formed in the frame which strengthen the frame. This is a matter of considerable importance because unless the frame is still, the machine is liable to vibrate unduly in mills where the floor is subjected to considerable jar. The gear F is a spiral or skew gear. It is made fast on the shaft C by a set screw f and preferably is set up against the bearing D as shown so that the bearing takes whatever thrust is given to the gear. Thus the thrust is dis tributed between the bearings on the several For this purpose a runway g is provided in the coiler plate and a rim or track g is formed on the under side of the coiler tube to fit therein. tube is provided with a spiral or skew gear 9 to be engaged by the gear F so that it shall be rotated thereby. I prefer that the teeth in these gears shall be at an angle of so that the coiler gear may be rotated in either direction as the rotation of the parts backward may sometimes be useful in cleaning the machine or otherwise.

In connection with my improvement I have shown only so much of the drawing frame as is necessary for the proper understanding of my invention, H, H being the calender rolls operated in the usual manner, J the clearer and K the trumpet arm carrying the trumpet 7a through which the sliver k is drawn and fed through the tube proper L and into the can VI.

The simplicity of my invention is apparent. To remove the coiler tube from the coiler plate it is only necessary to remove the usual cover and then lift out the tube;

The reduction of parts together with the distribution of the thrust and the consequent reduction of friction reduces the noise of the machine materially so that it may be called practically noiseless. The reduction of parts also reduces the cost materially both of the machine and of repairs. 7

What I claim as my invention is 1. In a drawing frame, a coiler plate, a coiler tube rotatably mounted on saidcoiler plate and having a skew gear on its periphery, a shaft running lengthwise of The periphery of the coiler said coiler plate and carrying askew gear meshing with said coiler tube gear, each of said skew gears being provided with teeth arranged at angles of substantially 45 to their respective axes, and a bearing for said shaft located on said coiler plate and engaging said shaft adjacent the gear thereon.

2. Ina drawing frame, a coiler plate of substantially uniform thickness having a channel running lengthwise of said plate near its rear edge, in combination with a coiler tube carrying a spiral gear on its periphery and a shaft carrying a spiral gear in mesh with said coiler tube gear, said shaft being located in said channel and said channel being enlarged opposite the axis of said coiler tube to receive said gear.

3. In a drawing frame, a coiler plate having a channel running lengthwise thereof, a

shaft bearing attached to the upper surface :1,

of said plate and projecting outward into said channel, a shaft supported by said bearing in said channel, a spiral gear on said shaft, said channel being recessed to receive said gear, and a coiler tube carrying a pegear on said coiler tube, asset forth.
